ABSTRACT:
An implantable artificial intraocular bipod lens comprising a medial light-focusing lens body having position fixation elements connected thereto. The fixation elements comprise a pair of straight elongated relatively thin and narrow legs extending tangentially in opposite directions from opposite sides of the lens body and lying along generally parallel lines. A relatively thin and narrow arcuate foot is located at the end of each of the legs. Each of the feet is longer and narrower than the width of the leg and preferably thicker than the leg. The feet extend obliquely in opposite directions. Preferably a suture/manipulation hole is provided in at least one of the legs spaced inwardly from the foot.
